I've been working on the taming of 'ol LeRoar my '64 Dodge Polara 4dr 324 poly with less goodies. I have sold my go fast goodies and am working to switch from racer to long distance cruiser. I don't think 'ol LeRoar likes being tamed :-)
I put in a stock hyd cam and the original 2 bbl manifold. I also got a new stock converter and rebuilt a new trans.. (I had busted the tailshaft housing on my original while racing.) I felt I had accomplished my goals with the poly engine and since I turned 70 it was time to drive the car more and break it less.
I have a very low vac at around 10-12" which wavers just a bit. This is indicative of late valve timing and/or not enough advance. The compression runs between 200 and 190psi on all cylinders. The cam/lifters and pushrods where all new as was the timing chain. The chain was installed straight up and I have a picture to prove it was put in right. The engine won't turn over 2600rpm without popping at the carb. It has been advanced and retarded and at about 10degBTDC it does best. I thought maybe the valves were not closing but it does not appear that way and the compression sure is high. The CR calculates at about 8.8/1 but that's a lot of psi for that low of a CR.
I do think I may not have tightened the valves down enough which is contrary to what would seem right with this problem. This dist was supporting 7500rpm previously and nothing was changed there so it should be good. (Mopar electronic w/orange box. Yes the orange box turned 7500rpm's!)
I will be swapping out the 2bbl manifold for my 4bbl 7503 that is prepped for EFI. Eventually I will switch to EFI but in the meantime I will run my 600cfm electric choke Eddy. I put it on this 2bbl manifold with an adapter which is less than desirable. Over the winter I will try a few things which will include checking my valve lash. (These hydraulics have adjustable rockers so they have to be set.) I will move the timing chain to the advanced setting to try that and I will be sure the dist is functioning properly. If I do not find a way to get the stock cam working right I will try the next step up in cams and start again.
It will come together if I keep working away at it.
